Government failure to prosecute offenders

Government pardoning of convicted human rights offenders
Arbitrary reduction of sentences for offenders after conviction
Inadequate punishment of international criminals in their own countries
Official amnesty for killers
In Argentina, for example, the government passed a series of decrees pardoning almost all those convicted as responsible for human rights abuses involving the forced disappearance of an estimated 15,000 people during the military dictatorship's operations in the 1970s and 1980s. Several Italian politicians accused in corruption scandals were pardoned in 1992 by emergency parliamentary decrees which decriminalized offences involving financing political parties with illegally-raised funds.
The wholesale pardoning of killers may churn stomachs, but an amnesty makes political sense. In the case of South Africa it helped secure a settlement. It is an important option in other regional conflicts.
